Why are ICU medical ventilators so expensive

Ventilators aid a patient respire by supporting the lungs to gasp and breathe out air. These apparatuses are used to treat patients agonizing from circumstances counting pneumonia, brain wounds and stroke.
The SARS-CoV-2 worm (which causes the COVID-19 illness) assaults the breathing system. When diseased, a patient s aptitude to respire is bargained. In minor cases, breathing or respiratory support can be provided using noninvasive means, such as delivering oxygen-rich air through a face mask.
In more unembellished cases, when a patient is diagnosed with severe respiratory misfortune, an aggressive method of respirational provision is obligatory. This is offered through a non-natural airway. A pipe committed to a ventilator is introduced into the patient s mouth or muzzle, or through a surgically-made hovel in the neck.
The main purpose of a ventilator made by the Ventilator Manufacturers is to drive or gust oxygen-rich air into the lungs; this is referred to as oxygenation . Ventilators also support the elimination of carbon dioxide from the lungs, and this is referred to as airing .
One rudimentary kind of ventilator is the Bag Valve Mask (BVM). The BVM, also recognized as the Ambu Bag, is functioned materially by a being cuddling a self-inflating bladder. This is an indispensable instrument for ambulance teams, first responders and critical care components. It is light, dense and easy to practice.
Though, in circumstances where a stable and skillful air swap (oxygen in, carbon dioxide out) is desired, motorized ventilators are obligatory.
